To oil 'whom 'it may concern:

Be it kno-wn' that i, FRANK Lesern Rienw iai-nosotr, e citizen of the United States, ren siding et Manifest, in the perish of @sito houle and Stets of" LouisiaJ-ps, have invented. certero. new ond useful improvements -in Fnvelops, oi which the 'following is o speedication.

This invention relates to safety envelope,

io ldesigned to be employed for protection of the contents, ond preventing surreptitions opening of the envelo and has for its ob sect to provide o simp y constructed device of this character which will veilectuolly pro' ,1,5 tect the contents and prevent the opening oi the enveiop by unauthorized persons Without this operation being observed by the receiver of the envelop.

lWith these and other objects view, the 2o mention consists in certem novel features of cornitrnction and arrangement of ports es herl vetter shown and described and speoiitelly pointed out in the claims.

in the drawings employed for illustrating the invention is shownvthe preferred form of embodiment of the same, and in these drew -Figure 1 is a view oi the blank from ywhich the envelop is constructed. Fi 2 is 'a view oi-the envelop complete and olded v and seeled.` Fig. 3 is an enlarged section on --thev line 3--3 of Fig 2. Fig. 4 e. perspective view, enlarged, of the motel secon ing' device detached. Fig is e sectional .deteii enlarged view off the safety locking Fig. 6 is e perspective' view of the improved envelop in position ready to receive its contents. F'O'. 7 e. perspective view taken from the si e opposite to that shown in Fi 6, with `Mythe' securing ilep thrust through t e slit in the body of the envelop, showing the position of the ietter just prior to the insertion therethrough ofthe securing device.

The improved envelop is constructed from i5 a singlesheet of paper in the form shown in Fig l, comprising a mein body portion with "two oppositely' extending lateral flopsy intermediate its 'ends with oneend of the sheet having its sides converging and with the 'other end of the sheet reduced in size.

The central portion of the sheet from which .the envelop is constructed is indicated at' i@ end the lateral flops et li-i2 extendn ing from the ends of the' central portion 10 the portion 1U forming one side of the pocket orv letter receiving portion of the envelop,

Extending treni the outer side oi the tlep i3 is the portion. having the converging sides above mentioned which ioin tvvo erts lo it?, the psrt i7 odspted to be oided upon the pert lo along.

Extending from the enter side'of the Hop i4 is the reduced portion shove' mentioned ond is also divided into twopfrts lig-T20 by e, dotted 2i, the port Eil adapted to be folded upon the port i9 et the' dotted'line.

The portion 1U is provided with spooed ei'ongeted apertures 22 23, vvleiie the p01- tion lo is provided opertires 2fi-25, theportion i? provided with similar apertures 2-27, the portion provided with sonner oper-tores pdb tion 2U provided 'with' sientas* sorter@ 30-f3l. are in elinement when the portion 27 istold ed upon the portion lo, as indicated in Fig f 6, end-the apertures 28 and 30 end 29-31 are respectively in elinementvvhe'n the portion The apertures 2dr-2o om 25e-i7 2O 1s folded upon the portion i9, es indicated .2S-3o sind 29-3i end then through apertures .Z4-26 and 25-4-27, es' indicated in Figs. 6 and 7., Oneo the arms oi the' fasten ing device is provided with oppositeiy ex- 4tending oblique points. 33 ot arrow shape,

While'the terminal oi the other erin is rovided with e socket 34: having on enlarge( iirner portion 35 and soontreoted throat or entrance 36, so that when the barbed or arrowshaped end of one arno. is thrust into the enlar ved interior 35 oi the heed 3e, theV inner en s oi" the berbs will catch behind the points 37 Within the heed and be retaifre'd thereby. it will. be understood that the points 33 'ere suciently resiient to be con treoted es they poss through the narrow throat 36 ond then er;` sind the refir of the portions 37, .and be thus ioolred in position,

as will beobvioun 39440, so that when the flaps 1112 are folded over the flap 14 their lower edges may velop is effected, first by the sealing of the In arranging the envelop for use thevfla 14 is, folded over upon the fia 10 along the ine 38 and the flaps .11-12 fo ded over the flap 14 with their ends overlapping, the flaps 11- -12 being guinmed, as indicated at be gummed to the outer surface of the flap 14,. the fia 12 being also gummed, as at 41, so that wlhen the outer ends of the flaps 11-12 are overlap ed they can be secured by gumming, as wl l be obvious.- tion 17 is then folded over upon the portion 16 and ummed thereto. This will dispose theenve op in condition for receiving its contents, as s own in Fig. 6, and after the contents are disposed in the pocket between the portion 10 ,and the flap 14, the reduced folded portion 19-20 is doubled over partly upon itself and its free end thrust through the slit 15, which causes it toproject beyond the portion'lO, as shown in Fig. 7. `The reduced portion 19-20 thus forms a partial closure and protection to the contents of the envelop. The member 32, when first inserted through the portion 10, is left with its Yarms projecting at right angles to the body of the envelop, as shown in Fig. 7, or in position to enable the folded flap 192O to be connected therewith by passing its a ertures over the respective ends'of the mem er 32,'the barbed end assingthrough one series of apertures an the socket enc passing through the other. The flap 13, together with the diverging folded portion 16-17, is then folded over the sealing flaps 11-12 and the .diverging portions 16-17 folded over the folded reduced portions 19-20, with its perforations assed over the protruding arms of the metal astening device, and the securing of the envelop completed by bending the two arms of the fastening device toward each other and thrusting the barbed. end into the socket, as before described, thus disposing the device into the position shown in liig. 2.

l The flap 13 and the edges of the diverging members 16,-17 are preferably provided with gumming material, as indicated at 42, so that the when closed.

By this means a double securing of the enummed surfaces and second. by the metal lgocking strip. As a still further protection, the exposed portion of the metal. strip 32 is provided with characters denoting the amount of postage required to mail the envelop, as indicated in Fig. 2, so that if the member 32 be cut loose and another substituted, the absence of these characters will denote thatthe envelop has been tampered with.

The.portion 10 of the envelop and the metal Strip 32 are provided with spaced s all apertures 43-45, through which rivet rfvices44 may be passed 'to enable the mem- -The porparts may be securely connected ber 32 to be attached immovably to the body of the envelo l It will thus be obvious that a very simply constructed envelop is produced which effectually prevents the contents from surreptitious handling, and which will indicate to the receiver whether or not the securing means has been tampered with.

The envelop may be made of various sizes,

and of any suitable material adapted to the purposes for which it is employed.

Having thus described the nature of the invention, what is claimed as new is 1. An envelop blank comprising a sheet of paper divided by folding lines into a front portion havingsealing flaps at the ends and a back portion extending from one side and a closure portion extending from i the other side, said back portion and closure portion being uniform in size with the front portion. and with a slitat the juncture of the closure portion and front portion, said back portion having a sealing flap extending from its free edge and of less length than the back portion, whereby an' envelop may be formed by folding the back portion over the front por tion and folding the end flaps over the back 4portion and passing the reduced sealing flap through said slit and passing the closure portion with its sealing iiap around the folded front and back portions with the reduced sealing hap overlapping th'ev sealing flap of the closure portion.

2. AnI envelop comprising a'sheet of paper divided by folding lines into a front portion having sealing iiaps at the ends and a back flapextending from one side and a closure flap extending from the other side and with a slit at the juncture of the closure iiap and the front portion said back flap having a reduced sealing fiap extending from its free edge and said closure flap having a sealing iiap extending from its free edge with the outer portions of said sealing iiaps folded upon themselves and cemented, and said front portionand sealing flaps provided with spaced apertures adapted tol register when the envelop is in folded position, metal fastening device having yieldable barbs at one end and a socket having an enlarged interior and adaptedto re ceive and hold said barbs at the other end and adapted to be bent into U-form and thrust through said apertures and the barbed end inserted into the socket after the envelop is closed, to secure the same.
